Strong Customer Authentication

Payer Authentication/3-D Secure is used for Strong Consumer Authentication (SCA) in e-commerce payments. Some card issuers require cardholders to authenticate with a 3-D Secure challenge when saving their card with a merchant. If you operate in a region where this is common, you can enable this setting to require a challenge each time a customer saves a card. To enforce SCA, choose

Yes

in the Enforce Strong Customer Authentication setting in the admin configuration panel.

If SCA is not enforced and an issuer requires it, this extension will replay the transaction and request the challenge.
